I have a hen who's been sitting on two eggs, one of which hatched today. Yesterday, we brought home two week-old chicks. Any chance we could sneak them under her to take care of? Or should we keep them separate? The other egg should've hatched yesterday, but we don't hear any peeping.
and Welcome To BYC! X3 you can try it and it may very well work. Keep a very close eye on them to be sure she accepts the chicks. And then I would have the broody in a cage or confined area and food and water very close to the entrance of the nest, so the week olds can get food and water with out getting any distance away from the broody, that may keep her on the nest a day or two longer for the just hatched one.
